i A further ebject tor tlle ifiventlOn is the I provisionof lockingmembersfor clamps, so 1 as to insurethe proper holding of the-clamps inengagement with th l ff ll. p V further" object of the I invention isthe I provision of.

A still furtherobjeet ofthe invention is the provision of arailroadjspike extractor'of the above character," which will be durableend efiicient in use; one tliatj 'will be simple and easy tolnanufac'ture, and one 'which can placed uponthe market at reasonablecost."

v Referring to the drawings in detail, where in similar referencecharacters designate coremployed for holding the rails on the ties.

I The improved spike puller Acoinprisesza base block 20 which canhavefits outer face curved transversely if preferred. The lower face ofthe base block 20 is providedwith a longitudinally extending groove 21for snugly receiving. the head or ball "12 ota-rail and the flanges '22defined by said groove engage the opposite sides oftheballof the; railand prevent lateral shifting of the block; 7 -The block'is'provided onitsupper face adijacenteach end thereof with transversely extendinggrooves 23 and intermediate its ends i and between the grooves 23 with acentral transverse groove 24. The block is provided with alongitudinally extending central'bore 25 which receives a removablelongitudinally extending pivot 26 which, as shown, terminates short ofthe endtransverse groove 23. This pin 26 has rockably mounted thereonthe operating lever 27 of the spike puller and the groove 24. is soarranged that the lever can .be

swung from one side of the block to the other and the lever on each sideand above its pivot carries spike extracting claws 28 and 29. Theseclawsare rockably carried by the lever and so arranged that one clawcan. be used for'one side of the rail forjextractingspikes; while theother claw can housed on the other side of the rail for extractingspikes. The J lever'27, as shown, isprovided with a rela-' tively shorthandle, but' it'is to be understood that an extension hand therewith ifdesired.

' In order to hold thebase block on the rail grip can beassociatedagainst longitudinal movement and inorder .to further bracethe sameagainst lateral shifting during the extracting of a spike, novelclamps 30 and 31 arecarried by the opposite ends of the block. 7 Eachclamp includes jaws 32' and 33 which depend from the opposite sides ofthe base block 21 and these jawshave formed on their upper end inwardlyextending pivot ears 34. The base block itself on thefopp'osite side ofthe longitudinal bore 25 is provided with side bores 35 which extendthrough or communicate withthe' end: transverse grooves 23 and the cars34 are placed in said grooves after which the pivot pins 36'are slid inthe bores 35. This effectively holdsthe jaws in position for f swingingmovement. The lower ends of the jaws. are provided iwith inwardlydirected books 37 for engaging the base flanges 14 of the rails andthejaws above the hooks are provided with blocks 38 for clamping en-.gagement with the-Web ofthe rail. HA contractile coil spring connectsthe two jaws together on each side of the pivot'point thereof andnormally tends to swing. the jaws in open position out of clampingengagement with therailr '1.

When it is desired to clamp the base block inposition swinginglatches40, carried by the base block are moved into engagement with the jawsand these latches effectively holdthej aws in clamping position. Each ofthe swinging latchesAO carry a manipulating handle 41. v.

In operation of my; improved device, when 'itis desired to extract thespikes from the tie the baseblock is placed on the rail inthe desiredposition and held in place by the;

1 clamps after which the lever 27 is swung to one side and the claw' isinserted over the headof the'spike. Thelever is now moved upwardly. andthe spike will be conveniently and expeditiously pulled from the tie. i

In a device of this kind, spikes can be cone veniently removed from theties on high 'trestles andjthe like inthat spikes can be removed fromboth sides of the rail from the center of the trestles. Y Y

The spike puller can be conveniently moved along the rail from place toplace by grasping the pivoted bail handles 42 carried by.

each end of the block for this purpose.

Changes in details maybe made Without departing fromthe spirit or thescope of this invention, but 1 Y What I claim as new is: J E 71., Arailroad spike puller comprising a base block, means carried by theopposite ends of thebase blockfor clamping engagement ing means forengaging the base flanges of a rail, means carried by the blOCk-IEOI"holding the jaws" in gripping contact with the-raiL-a swingingoperatmg'lever carriedfby the base block, intermediate the'clamps forswinging movement of eachsideofthe base block, and pivot-ed clawscarried by the leverabove and on the same side of the pivotpointthereof.
